Computer readable storage medium and RFID (radio frequency identification) system using same

Abstract

The invention relates to the field of radio frequency identification tag identification, in particular to a computer readable storage medium and an RFID (radio frequency identification) system using the same. A computer program is stored in the medium and can be executed by the RFID system. By the aid of a stream key generator based on an AES-LFSR (advanced encryption standard-linear feedback shift register), an AES encryption-decryption algorithm is fused into a front end generating a stream key sequence, security of a stream key can be improved when randomness is ensured. By the aid of a mode of the stream key, difference of secret keys in each communication process is ensured, man-in-the-middle attack can be effectively resisted, the problems of security caused after the stream key is stolen or leaked in the authentication process are solved, and randomness and reliability of data are enhanced.

Description

technical field [0001] The invention relates to the field of radio frequency electronic tag identification, in particular to a computer-readable storage medium and an RFID system using the medium. There is a computer program stored in the medium, and the computer program can be executed by a processor of the RFID system. Background technique [0002] With the rapid development of the Internet of Things, radio frequency identification (RFID, Radio Frequency Identification) technology has been widely used in today's society. Because of the wide application of radio frequency identification technology in information exchange, its security has also begun to be valued. The RFID system itself is an open identification system, and its communication channel is open. Attackers can illegally steal the communication information between the reader and the electronic tag of the RFID system. Therefore, the RFID system has certain security risks. Moreover, the security of the chip itself o...

Problems solved by technology

The RFID system itself is an open identification system, and its communication channel is open. Attackers can illegally steal the communication information between the reader and the electronic tag of the RFID system. Therefore, the RFID system has certain security risks.

Moreover, the security of the chip itself of the electronic tag is also poor, and it is easy to be cracked, and the security of its transmitted data information has become an urgent issue.

The traditional RFID system encryption method is to encrypt the communication data through the stream key, etc., and the receiver decrypts the data after receiving it, such as the LFSR encryption and decryption algorithm based on the linear feedback shift register LFSR, but if the key is encrypted during data transmission The security of data transmission cannot be guaranteed even if it is stolen or leaked
